Plus they also make it easy to run the AM churro (
http://www.andymark.com/product-p/am-churro.htm) in between the gear boxes to stop the sagging from happening as much. Tap the ends of each rod and shove some 1/4-20 bolts in from the gearbox side. Most of the teams that had these gearbox sagging issues I noticed had nothing in between their gearboxes. Even the weight of 3 CIM motors can cause that sagging and that alone can shred a gearbox from alignment issues.
See the attached photo. Every team should be supporting their gearboxes in some way because it will also stiffen your frame up.
